The matter of digital platforms and their treatment in competition law have attracted much attention. Not only through investigations into Google, Face-book and Amazon, but also with the issuing of several reports. The antitrust debate surrounding digital platforms is huge and encompasses...

This POLICY BULLETIN examines the potential impact of the proposed Cingular/AT&T Wireless merger on both (a) the performance in the national wireless industry; and (b) the potential for wireless "intermodal" competition with fixed line service. After performing both an event study and merger...

This paper identifies substantial flaws in how U.S. government agencies and courts assess the impact of proposed mergers by firms using broadband networks to reach consumers. Based on current market definitions, consumer impact assessments and economic doctrine, antitrust enforcement agencies...

We analyze the welfare effects of parity rules, prevalent in telecommunications and other regulated industries, that force a vertically-integrated input monopolist to treat its own downstream affiliate and downstream competitors comparably in terms of input price and quality. When input pricing...

Algorithms, especially those based on artificial intelligence, play an increasingly important role in our economy. They are used by market participants to make pricing, output, quality, and inventory decisions; to predict market entry, expansion, and exit; and to predict regulatory moves. In a...

While the content of margin squeeze has been largely provided by the case-law of European courts detailing how the foreclosure of competitors occurs as a direct result of its usage, some key conceptual issues have remained unresolved. These issues are not confined to how to identify abusive...

We analyze the welfare effects of “parity” rules that force a vertically-integrated input monopolist (VIM) to treat downstream affiliates and competitors alike in terms of price and quality. We find that input-quality parity can lower social welfare when input pricing is unregulated. In...

This paper provides a simple model that examines a firmfs incentive to invest in a network infrastructure through coalition formation in an open access environment with a deregulated retail market. A regulator faces a dilemma between inducing an incentive for efficient investment and reducing...

I study the role of unilateral strategic contracts for firms active in markets with price competition and endogenous entry. Traditional results change substantially when the market structure is endogenous rather than exogenous. They concern 1) contracts of managerial delegation to non-profit...
